Coping with Megacities: As millions of people migrated to “first-tier cities” (一线城市) like Beijing, Shanghai, and Shenzhen, problems like insane housing prices, gridlocked traffic, and pollution became critical. The government's solution was not to stop growth, but to redirect it into planned, surrounding satellite cities.
Comparison with Western “Suburbs”: An American suburb or a British “commuter town” is often primarily residential—a place people leave in the morning for work and return to at night. A Chinese 卫星城, in theory, is designed to be more holistic. The goal is to relocate not just people, but entire industries, universities, and government offices to these new urban centers. For example, many manufacturing plants have moved from central Shanghai to nearby satellite cities like Kunshan (昆山). This planned economic self-sufficiency is the key differentiator.
Social Impact: For residents, moving to a 卫星城 is a trade-off. They might gain a larger, more affordable apartment and a cleaner environment, but they often face longer commutes (if their job is still in the main city) and a sense of being disconnected from the cultural heart of the metropolis.
